I have several SSH keys on my ubuntu 20.04 host machine. They all can successfully connect to my vbox Debian 10.5 server using the following format:
ssh -t -i ~/.ssh/id_rsa [email protected]
However, I am attempting to add a new key for a new website on the vbox server and the above command only resuts in
Received disconnect from 192.168.0.84 port 22:2: Too many authentication failures
when I run ssh -vvv -t -i ~/.ssh/id_rsa [email protected] I can confirm that the command connects to the correct ip address and the correct ssh key is being used.
The .pub key was uploaded to server via the ISPC gui using the same method as all of my other keys.
If I add -o 'IdentitiesOnly=yes' or -o IdentitiesOnly=yes, the connection is made, but then I am asked to provide a non-existing password, and then disconnects.
I also verified that the .ssh directory has 700 permissions and the keys have 600 permissions.
So I am a little baffled at the moment. Any tips
